Abstract

The invention relates to an apparatus and a method for joining a pipe conduit to a drilling device, expanding device or pull-in device, in which a pulling-force generator arranged in the drilling device, expanding device or pull-in device exerts a compressive force on a pipe conduit, to be pulled in, via a pulling means and an adapter and thereby holds the individual short pipes of the pipe conduit together and reduces the mechanical stress to which the short pipes are subjected.
